intrll tait-a CHARLES ROBINSON, OF BOSTON, MASSACHUSETTS.

Letters Patent No. 93,908, dated .August 17, 1869.

The Schedule referred to' in these LettersPatent and making part of the same.

To all whom it may concern:

Beit known that I, CHARLES ROBINSON, of Boston, in the county of Suffolk, and State of Massachusetts, have invented an Improved Arrow-Gun; and I do hereby declare thatthe following is a full and exact description thereof, reference being had to the accom'- panying drawings, making part of this specification- Figure l being a top view of the gun, and

Figure 2, a side view thereof.

Like letters designate corresponding parts in both figures. d

This gun is designed as a substitute for the cross-v bow, and it may be used in place of the bow and arrow. I also contemplate its use for the manual exercise, by making it of the size and; general form of the regulation-niusket. o

ThestockA is grooved a't a for the-reception of the arrow B, except a rporton, b, at' the muzzle, which may be enclosed around theA bore, in continuation of the groove. y

The arrow, of ordinary form, may have its notched or feather-end rest in anotcl1,c, at the rear end of the groove a, a little higher than .the groove, so as to raise the arrow into position to take the cord when sprung, the notch also keeping the feather-edge upright.

One feature of my improvements consists in the use I of an elast-ic band,.fl, stretched around or attached to the stock, about "in the position shown, under which' the arrow goes. It serves to hold the arrow securely in: position,before discharging,'and also to guide it more accurately and steadily in its discharge.

Instead of a bow, I employan elasticcord, O, for throwing the arrow. It passes through, or is attached to the stock at f, near. the' muzzle, and forms a loop, which is of the proper length to. be stretched with the requisite force, when brought back behind the arrow.

When the cord is notiu use forthrowing the arrow, it is brought below the stock and fastened around a knob or hook, g, or its equivalent, being stretched slightly when thus fastened'. It is thus held from dangling, when carrying and handling the gun.

For the lock, orvcatch and trigger, to hold the cord,

when set for tiling, I use a simple spring-wire, D, one end, h, being driven into the stock; then, forward ot' that, having a projection, or bend, li, for the catch; thence extending down through an aperture, or slot, l, in the stock, and terminating below, with a projection or trigger, m.

The whol'e form and arrangement are substantially as represented.

It is very simple and cheap, but as convenient and effective as any other device'for the purpose.

Instead of making the trigger' elastic initself, it may be pivoted to or in the stock, and a slight spring be used to keep it in position to receive the cord; the latter not being necessary, however, the essential feature g of the device being a single piece, of any suitable form, with a hook, or catch-projection, i, which holds the` cord, without the assistance of a detent, and discharges the cord by slipping downward, away from the same. l

I ain aware that an elastic cord has been used to throw balls and pellets, Vand to spring forward plungerrods in toy-guns, but I am not aware that a springcord has ever before been employed as a substitute for the -bow' and string, on a gun for throwing arrows,
